You have to read the message carefully: plperl.so is trying to invoke
libperl.so, and that file is the one that's not being found.

This suggests to me that your Perl installation isn't quite the same as
the one the RPM was built against. Try
readelf -d /usr/lib/pgsql/plperl.so
and see if there's an RPATH entry. On my plperl.so I see
0x0000000f (RPATH) Library rpath: [/usr/lib/perl5/5.8.5/i386-linux-thread-multi/CORE]
and indeed I have /usr/lib/perl5/5.8.5/i386-linux-thread-multi/CORE/libperl.so
so everything works. But with all those version numbers buried in the
path, a slightly different Perl vintage would make it break.
